[PULL 05/13] linux-user: fix O_NONBLOCK usage for hppa target |

From: Helge Deller <deller@gmx.de>
Historically the parisc linux port tried to be compatible with HP-UX
userspace and as such defined the O_NONBLOCK constant to 0200004 to
emulate separate NDELAY & NONBLOCK values.
Since parisc was the only Linux platform which had two bits set, this
produced various userspace issues. Finally it was decided to drop the
(never completed) HP-UX compatibilty, which is why O_NONBLOCK was
changed upstream to only have one bit set in future with this commit:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=75ae04206a4d0e4f541c1d692b7febd1c0fdb814
This patch simply adjusts the value for qemu-user too.
